领英数据显示，视频广告观看进度至少为 50% 的人群可以作为再营销受众。

The statement is incorrect. LinkedIn data shows that audiences who watch at least 25% of a video ad can be used for retargeting. This threshold is set to capture a broader audience that has demonstrated some level of engagement with the video content, making them suitable for subsequent retargeting campaigns. Setting the threshold at 50% would significantly narrow the retargeting audience, potentially missing out on many interested prospects.
